*1 For the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower, it is the gauge of a cable with the continuous maximum permissible
temperature of 75°C (HIV cable (600 V grade heat-resistant PVC insulated wire), etc.). It assumes a surrounding air temperature of 50°C or lower
and the wiring distance of 20 m or shorter.
For the FR-A820-03800(75K) or higher, FR-A840-02160(75K) or higher, it is the gauge of the cable with the continuous maximum permissible
temperature of 90°C or higher. It assumes a surrounding air temperature of 50°C or lower and in-enclosure wiring.
*2 For all the 200 V class capacities and FR-A840-01160(45K) or lower, it is the gauge of a cable with the continuous maximum permissible
temperature of 75°C (THHW cable). It assumes a surrounding air temperature of 40°C or lower and the wiring distance of 20 m or shorter.
For the FR-A840-01800(55K) or higher, it is the gauge of a cable with the continuous maximum permissible temperature of 90°C (THHN cable).
It assumes a surrounding air temperature of 40°C or lower and in-enclosure wiring.
(For the use in the United States or Canada, refer to "Instructions for UL and cUL" in the Instruction Manual (Startup) or Instruction Manual
(Hardware).)
*3 For the FR-A820-00770(15K) or lower and the FR-A840-01160(45K) or lower, it is the gauge of a cable with the continuous maximum permissible
temperature of 70°C (PVC cable). It assumes a surrounding air temperature of 40°C or lower and the wiring distance of 20 m or shorter.
For the FR-A820-00930(18.5K) or higher and the FR-A840-01800(55K) or higher, it is the gauge of a cable with the continuous maximum
permissible temperature of 90°C (XLPE cable). It assumes a surrounding air temperature of 40°C or lower and in-enclosure wiring.
(Selection example mainly for use in Europe.)
*4 The terminal screw size indicates the size of a terminal screw for R/L1, S/L2, T/L3, U, V, W, PR, PX, P/+, N/-, P1, and a screw for earthing
(grounding).
The screw size for terminals PR and PX on FR-A820-00340(5.5K) and FR-A820-00490(7.5K) is indicated in parentheses.
The screw size for earthing (grounding) terminal on FR-A820-00930(18.5K) or higher and FR-A840-04320(160K) or higher is indicated in
parentheses.
The screw size for terminal P/+ for option connection on the FR-A840-03250(110K) and FR-A840-03610(132K) is indicated in parentheses.
The line voltage drop can be calculated by the following formula:
× wire resistance [mΩ/m] × wiring distance [m] × current [A]
Line voltage drop [V] =
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
reduction) in the low speed range.
NOTE
• Tighten the terminal screw to the specified torque.
A screw that has been tightened too loosely can cause a short circuit or malfunction.
A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.
